Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To firmly bond a bonding layer and a main conductor layer together so as to effectively prevent mutual diffusion from occurring between them by a method wherein a barrier layer of nickel-chromium is interposed between the bonding layer of titanium and the main conductor layer of gold. SOLUTION: A circuit wiring 2 is deposited on the upside of an insulating board 1 through a thin film forming technique. The circuit wiring 2 is equipped with a three-layered structure composed of a titanium bonding layer 3, a barrier layer 4, and a main conductor layer 5.
